When a user tries to upload after upgrading, they get this message:
An error occurred while attempting to create a folder for your files. If the problem persists, please notify the webmaster
I figured that either the path was wrong or something happened to the CHMOD again, but I checked them both and everything is entered correctly, I even resaved the settings in AdminCP.
Now about the .htaccess... I hadn't had a problem with it, but a user told me he saw red X's for all of the pictures. I checked on IE right after he said that and all of them were showing just like he said they were, but it was working on FireFox and on IE earlier, so I have no idea what's going on there. I disabled it for the time being until I or somebody else figures out what's going on. ;x
